Data correction for a sensor

A system comprising:

• a sensor chip including:
• a sense component configured to sense motion and output a sensed signal;
• a drive circuitry and a sense circuitry, wherein the sense circuitry includes:
• a sampling unit configured to receive and sample the sensed signal with a sensor clocking signal received from the drive circuitry to generate a plurality of sampled values;
• and
• an interpolator within the sense circuitry configured to receive the plurality of sampled values from the sampling unit, and wherein the interpolator is further configured to receive the sensor clocking signal and a reference clocking signal external to the sensor chip, and wherein the interpolator is configured to interpolate the plurality of sampled values based on the reference clocking signal and further based on the sensor clocking signal to generate a plurality of estimated sampled values;
• and
• a host processor external to the sensor chip, wherein the host processor operates by the reference clocking signal and is configured to receive the interpolated plurality of estimated sampled values from the sensor chip, wherein a correction to a frequency or sampling error is made by the sensor chip to reduce power consumption by the host processor.

A method comprising:

• sensing a motion to generate a sensed signal;
• sampling the sensed signal, within a sense circuitry, with a sensor clocking signal received from a drive circuitry to generate a plurality of sampled values, wherein the sensor clocking signal is received from environment within a sensor chip;
• receiving a reference clock signal, wherein the reference clock signal is received from external environment of the sensor chip;
• and
• interpolating the plurality of sampled values within the sense circuitry based on the sensor clocking signal and the reference clock signal to generate an interpolated value.
